They used the wrong covers for the wrong volumes!
OK, maybe this isn't a big deal, as it doesn't really have anything to do with the show itself or the dub, but the DVD covers are mixed up. Each one (save the last volume,) has an image from an episode that's not on that particular disk, but a different one in the series.
Volume one SHOULD have the picture of the piano-playing ghost.
Volume two should have the picture of the Grim Reaper-type ghost (the one that visits children left alone at night.)
Volume three could either be the picture of the possesed rabbit, or the ghost nurse.
Volume four...well, maybe a picture of the ghost painter, the one with the skull face that sends Satsuki and Hajime back in time?
On a totally unrelated note, I think you could make a drinking game out of Ghost Stories. Each person takes one shot every time Momoko says the name Jesus. (Works only if you're watching the dub.) Also take one shot everytime Satsuki's panties are exposed to the boys. (Do NOT count the time when it just turns out she's wearing Nike bike shorts.) And take one shot anytime a character in the dub breaks the fourth wall. Unfortunetly I can't think of anymore triggers, but if you're watching the whole series that should get anyone who's not an experienced drinker good and drunk.
